Cr15Ni60/60Ni16Cr/NiCr6015 Nickel-Chromium-Iron Alloys The Top-Notch Material for Heating Element Resistor

Cr15Ni60 is a high-temperature resistant electric heating alloy, characterized by its excellent thermal stability and resistance to oxidation. Comprising 15% chromium and 60% nickel, along with a balance of iron and trace amounts of other elements, this alloy exhibits a low thermal expansion coefficient and high electrical resistance. It is valued for its ability to maintain these properties even at elevated temperatures, making it suitable for applications in furnaces and other high-heat environments. The alloy's resistance to oxidation is exceptional, allowing it to perform well in air at temperatures up to 1000°C with minimal degradation. Its linear increase in electrical resistivity with temperature change is another beneficial characteristic for precise temperature control in industrial processes. Cr15Ni60's combination of strength, resistance, and stability positions it as a preferred material in the manufacturing of electric heating elements and other components that require high-temperature endurance.

0.1<D<0.3, T>0.2 ≥600 MPa ≥20%

Some key features of Cr15Ni60 include:

  1. Chemical Composition: Cr15Ni60 is composed primarily of chromium (15%) and nickel (60%), with the remainder being iron and trace amounts of other elements like manganese and silicon
  2. High-Temperature Resistance: The alloy exhibits excellent resistance to high temperatures, with a melting point of around 1390°C and capable of withstanding continuous use up to 1100°C
  3. Oxidation Resistance: Thanks to the chromium content, Cr15Ni60 forms a stable chromium oxide (Cr2O3) layer at high temperatures, which protects the alloy from further oxidation
  4. Mechanical Strength: Cr15Ni60 maintains good mechanical strength at high temperatures, with a tensile strength of approximately 600 MPa at room temperature, and it retains strength even at elevated temperatures
  5. Electrical Resistivity: The alloy has a high electrical resistivity of about 1.11 Ω·mm²/m, which is beneficial for applications requiring high resistance at lower voltages
  6. Thermal Stability: Cr15Ni60 demonstrates good thermal stability, with a low temperature coefficient of resistance, ensuring stable resistance values across a wide temperature range
  7. Corrosion Resistance: The alloy shows good general corrosion resistance, especially in oxidizing environments, due to the formation of a passive oxide layer
  8. Physical Properties: Cr15Ni60 has a density of 8.2 g/cm³ and a thermal expansion coefficient of 13.0×10⁻⁶/°C (20-1000°C), which contributes to its dimensional stability at high temperatures

These characteristics make Cr15Ni60 an ideal material for high-temperature electrical heating elements, industrial furnace components, and other applications where high-temperature stability and resistance are required.

Applications:

  • Heating Elements: Ideal for use in periodic heat treatment furnaces operating below 900°C.
  • High-End Electric Heating Devices: Used in high-quality electric heating wires for appliances.
  • Resistance Boxes: Employed in high-quality resistance boxes for precise electrical measurements.

Overall, Cr15Ni60 is a reliable choice for high-temperature applications requiring stable electrical resistance and excellent corrosion resistance.
